We compare the transition barrier that accompanies a first-order phase transition
in the canonical and microcanonical ensemble. This is directly encoded in the probability
distributions of standard Metropolis Monte Carlo simulations and a proper microcanonical
sampling technique. For the example of droplet formation, we find that in both ensembles the
transition barrier scales as expected but that the barrier is much smaller in the microcanonical
ensemble. In addition its growth with system size is weaker which will enhance this difference
for larger systems. We provide an intuitive physical explanation for this observation
